Call recognition in birds is important so energy and time are not wasted. Many studies have used heterospecific calls that were evolutionarily distant from the species being tested to show that recognition was possible. This study looked at species recognition of both an evolutionary distant species (common potoo, Nyctibius griseus: Nyctibiidae) and of a species in the same family (magpie jay, Calocitta formosa: Corvidae) in brown jays (Cyanocorax morio: Corvidae). Three different calls (brown jay, magpie jay, and common potoo) were played in ten different territories of brown jays in the Monteverde area during the dry season. Results suggested that brown jays could distinguish their call from the other two species (p = 0.019). Brown jays a...
